DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 245,605, dated August16, 1881.

Application filed May 16, 1881. (No model.)

To all whom it may concern.-

Be it known that I, CALEB BRINTON, of Ohica-go, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Door-Hangers, of which the following, in connection with theaccompanying drawings, is a specification.

In the drawings, Figure 1 is a side elevation of a door-hanger embodyingmy improvements. Fig. 2 is an edge view of the same closed. Fig. 3 is aside elevation showing a modification in the construction of the hanger.Fig. 4 is a detail, in perspective, of the hinge and guidestrip. Fig. 5is a section in the plane of the line at w of Fig. 4, and Fig. 6 is anend view of one of the levers.

Like letters of reference indicate like parts.

A and A represent bars, arms, or levers, arranged parallel, one end ofeach of which is hinged to the rear edge of the door B, as indicated ata, or in any suitable way admitting of the other ends of the said leversbeing moved or swung vertically. 0 and c are also parallel andvertically-swingin g levers, and these are hinged to a stud or post, D,of the building to the rear of the door. The levers A and 0 meet eachother, and are pivoted together in such a way as to permit the verticalmovement already referred to. The lever c is provided with a roller, E,which lever, includin g its roller, is about twice the length of eitherof the other levers, so as to allow the roller E to lie on or againstthe rear edge of the door. The lever A meets the central post of thelever 0, and is there pivoted to it. The levers A, A, and c are of equallength, which levers, including lever c, are joined to the ends of thevertical central guide-bar, F, at the point where these levers arerespectively pivoted to each other.

It will be perceived from the foregoing description that the door willbe suspended by the hanger, and may be moved horizontally or parallel tothe floor in opening or closing it. The guide-bar F causes the upper andlower sets of levers to move together, and, in conjunction with lever c,prevents the door from tilting and sagging. The joints connecting thelevers to each other and to the guide-bar should stand above or belowthe other joints when the door is open, to avoid a dead-center.

lieving the hangers from too great weight and strain. In thisarrangement the spring 0 is omitted, as the friction of the roller Eupon the floor overcomes the tendency of the hangers to move the door,as hereinafter explained. The rear edge of the door may pass thepost T.

The object of the roller E is simply to lessen friction, which wouldresult from pressure of the lever 0 directly against the edge of thedoor or other post. This object is further accomplished by theemployment of a guide or way, b, for said roller to travel upon. Whenthe track I) is employed it may be bowed or curved, causing the door todescribe the arc of a circle, thereby permitting the door, when closed,to fit snug to its frame at either the top or bottom of the door,according tothe direction of the curve, without the door beingobstructed in its movements. When only one roller, E, is employed, itmay be arranged to operate in either the upper or lower set of levcrs.

G G are the hinge-plates which are applied to the door-post or building.These plates have deep notches O O, which are rabbeted or recessed, asshown in Fig. 5, to receive the stem and head of a headed pin or stud,so that said pin or stud can be removed from the plate only by beingmoved out of the open end of said notches. H is a strip attached to thewall or studding, and having in its face a groove or way, d. This stripleads from the doorway to the notch G. The longest part of plateG closesthe end of the groove (1, as shown in Fig. 4.

I I are headed pins or studs on the inner ends of levers c and c.

To adjust the hanger to the hinges G Gin a hollow wall, the studs I Iare placed in the forward ends of the grooves d d, and are then forcedback into the notchesOC. The weight of the door upon the hanger servesto keep the studs I I in the notches O C. By this means the hanger anddoor can be attached to or detached from its hinges in the recessbetween walls after said'walls are finished.

In order to conveniently remove the door and hanger from betweenfinished walls, I also employ a button or buffer, J, which is pivotedhorizontally to the rear edge of the door. The ends of said buffer areintercepted by projections provided between the walls, thus limiting themovement of the door and hanger. Said bufl'er can be turned to avertical position by inserting a thin instrument between the door andits frame, when the door can be moved from between walls, thus enablingrepairs to be conveniently made.

In the lower end of the door there is a groove running the entire widthof the door, in which the guide 1' operates to keep the door in avertical position and prevent it from rubbing against its frame. Asimilar guide and groove may also be employed at the top of the door.

It is obvious that the gravitation or weight of the hanger will tend topush and hold the door either open or closed, according to the positionof the hanger. To overcome this tendency I apply a bracket, 0, to therear edge of the door, through which bracket I pass a bolt, 0, which isyoked at its lower end to the spindle of the roller E.

Between the bracket 0 and the upper or threaded end of the bolt 0, Iarrange an open spiral spring, 0, which spring is held in place and itstension regulated by means of the screwnut h. It will now be perceivedthat as the hanger tends to move the door this tendency will be overcomeby the spring 6.

It is obvious that other means may be employed to perform the functionof the spring, and when it is desired to have the hanger close doors orgates this spring, or its equivalent, may be dispensed withadvantageously.

The screw-holes in the door-hinges may be slotted to facilitate thevertical adjustment of the door, as indicated'at f j.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, in a door-hanger, ofan upper and lower set or seriesof extensible and retractible jointed or pivoted levers and a verticalcentral guide rod or bar, F, jointed or pivoted to each of the saidseries, substantially as and for the purposes set forth.

2. In a door-hanger consisting of an upper and lower set or series ofextensible and retractible jointed or pivoted levers, the extended lever0, having a free or loose end, carrying an anti-friction roller, E,substantially as and for the purposes specified.

3. The combination, in a door-hanger consisting of an upper and lowerset or series of extensible and retractible jointed or pivoted levers,of the vertical central guide rod or bar,

F, jointed or pivoted to both the said sets, the lever 0, having afreeor loose end, and the roller E, mounted on the free or loose end of thelever 0.

4. The combination, in adoor-hanger, of the notched and rabbeted hingeplate G, the grooved guide H, and the extensible and retractible leverscarrying the headed pins or studs I, adapted to travel in the said guideand to enter the said plate, substantially as and for the purposesspecified.

5. The combination of the bracket 0, rod 0, spring a, and the extensibleand retractible levers of a door-hanger, substantially as and for thepurposes specified.
